sahilmgandhi 18:6a4db94011d3 15 ==============================================================================
sahilmgandhi 18:6a4db94011d3 16 ##### FLASH peripheral features #####
sahilmgandhi 18:6a4db94011d3 17 ==============================================================================
sahilmgandhi 18:6a4db94011d3 18
sahilmgandhi 18:6a4db94011d3 19 [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses
sahilmgandhi 18:6a4db94011d3 20 to the Flash memory. It implements the erase and program Flash memory operations
sahilmgandhi 18:6a4db94011d3 21 and the read and write protection mechanisms.
sahilmgandhi 18:6a4db94011d3 22
sahilmgandhi 18:6a4db94011d3 23 [..] The Flash memory interface accelerates code execution with a system of instruction
sahilmgandhi 18:6a4db94011d3 24 prefetch and cache lines.
sahilmgandhi 18:6a4db94011d3 25
sahilmgandhi 18:6a4db94011d3 26 [..] The FLASH main features are:
sahilmgandhi 18:6a4db94011d3 27 (+) Flash memory read operations
sahilmgandhi 18:6a4db94011d3 28 (+) Flash memory program/erase operations
sahilmgandhi 18:6a4db94011d3 29 (+) Read / write protections
sahilmgandhi 18:6a4db94011d3 30 (+) Prefetch on I-Code
sahilmgandhi 18:6a4db94011d3 31 (+) 64 cache lines of 128 bits on I-Code
sahilmgandhi 18:6a4db94011d3 32 (+) 8 cache lines of 128 bits on D-Code
sahilmgandhi 18:6a4db94011d3 33
sahilmgandhi 18:6a4db94011d3 34
sahilmgandhi 18:6a4db94011d3 35 ##### How to use this driver #####
sahilmgandhi 18:6a4db94011d3 36 ==============================================================================
sahilmgandhi 18:6a4db94011d3 37 [..]
sahilmgandhi 18:6a4db94011d3 38 This driver provides functions and macros to configure and program the FLASH
sahilmgandhi 18:6a4db94011d3 39 memory of all STM32F4xx devices.
sahilmgandhi 18:6a4db94011d3 40
sahilmgandhi 18:6a4db94011d3 41 (#) FLASH Memory IO Programming functions:
sahilmgandhi 18:6a4db94011d3 42 (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and
sahilmgandhi 18:6a4db94011d3 43 HAL_FLASH_Lock() functions
sahilmgandhi 18:6a4db94011d3 44 (++) Program functions: byte, half word, word and double word
sahilmgandhi 18:6a4db94011d3 45 (++) There Two modes of programming :
sahilmgandhi 18:6a4db94011d3 46 (+++) Polling mode using HAL_FLASH_Program() function
sahilmgandhi 18:6a4db94011d3 47 (+++) Interrupt mode using HAL_FLASH_Program_IT() function
sahilmgandhi 18:6a4db94011d3 48
sahilmgandhi 18:6a4db94011d3 49 (#) Interrupts and flags management functions :
sahilmgandhi 18:6a4db94011d3 50 (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler()
sahilmgandhi 18:6a4db94011d3 51 (++) Wait for last FLASH operation according to its status
sahilmgandhi 18:6a4db94011d3 52 (++) Get error flag status by calling HAL_SetErrorCode()
sahilmgandhi 18:6a4db94011d3 53
sahilmgandhi 18:6a4db94011d3 54 [..]
sahilmgandhi 18:6a4db94011d3 55 In addition to these functions, this driver includes a set of macros allowing
sahilmgandhi 18:6a4db94011d3 56 to handle the following operations:
sahilmgandhi 18:6a4db94011d3 57 (+) Set the latency
sahilmgandhi 18:6a4db94011d3 58 (+) Enable/Disable the prefetch buffer
sahilmgandhi 18:6a4db94011d3 59 (+) Enable/Disable the Instruction cache and the Data cache
sahilmgandhi 18:6a4db94011d3 60 (+) Reset the Instruction cache and the Data cache
sahilmgandhi 18:6a4db94011d3 61 (+) Enable/Disable the FLASH interrupts
sahilmgandhi 18:6a4db94011d3 62 (+) Monitor the FLASH flags status
